The QX316J is a highly integrated power control device that incorporates all the necessary components for a
complete, isolated IGBT gate drive circuit with fault protection and feedback into one SOP16 package.TTL
input logic levels allow direct interface with a microcontroller, and an optically isolated power output stage
drives IGBTs with power ratings of up to 150 A/1200 V. An output IC provides local protection for the IGBT to
prevent damage during over currents, and a second optical link provides a fully isolated fault status feedback
signal for the microcontroller. A built in “watchdog” circuit monitors the power stage supply voltage to
prevent IGBT caused by insufficient gate drive voltages. This integrated IGBT gate driver is designed to
increase the performance and reliability of a motor dri
